August 12, 2023 by Mcnair, B. There are six lava flow types or morphologies: pahoehoe, aa, blocky lava, pillow lava, sheet flow, and lobate. The first three are subaerial, and the last three are subaqueous (submarine, subglacial, and other subaqueous environments). These lava flow morphologies result from the pouring or oozing lava from a vent ...

Lava Flows. Pahoehoe Flows - Basaltic lava flows with low viscosity start to cool when exposed to the low temperature of the atmosphere. This causes a surface skin to form, although it is still very hot and behaves in a plastic fashion, capable of deformation. Such lava flows that initially have a smooth surface are called pahoehoe flows.

Basalt and its intrusive equivalents are by far the most abundant igneous rocks on the surface of the Earth and other rocky planets and satellites in the solar system. The prominent maria on the Moon (Fig. 5) are composed of basaltic lava, and basalt makes up much of the surface of Mercury, Venus, Mars and Io (the innermost moon of Jupiter ...

question. The answer would be flood basalt. This is the outcome of a huge volcanic eruption or sequence of eruptions that covers large expanses of land or the ocean floor with basalt lava. The development and effects of a flood basalt hinge on a variety of factors, like latitude, continental configuration, rate, volume, period of eruption, the ...
